Abstract (en)
[origin: EP1672067A1] Non-amino organic acids such as succinic acid, malic acid and fumaric acid are produced by reacting bacterial cells or treated bacterial cells of a coryneform bacterium with an organic raw material in an aqueous medium containing magnesium carbonate and/or magnesium hydroxide, and a certain range of concentration of a monovalent cation, while maintaining the pH within a certain range without increasing the volume of the aqueous medium.
